(mime attachment!) debug function: first time weird behavior

(mime attachment!) debug function: first time weird behavior

[An attachment was originally included here]

I have attached a function which I have been working on.

It archives information gathered from 'whois' (so I don't have to wait for  
internic to respond if I have already run 'whois' on the archive.

The first time it is run it says:

/usr/local/lib/whois/ is a directory
 whois: Have info archived: /usr/local/lib/whois/

If I run it again, it works fine.

I am totally clueless as to why this is happening but it is easily reproducable.

Any help greatly appreciated.

Er, yes. :-)

        DIR=/usr/local/lib/whois 
        FILE=$DIR/$LOOKFOR 
        LOOKFOR=`echo $* | awk '{print $NF}'` 

Have you considered that perhaps you should assign a value to LOOKFORE
-before- you use it to assign to another variable?

        DIR=/usr/local/lib/whois 
        LOOKFOR=`echo $* | awk '{print $NF}'` 
        FILE=$DIR/$LOOKFOR 

Also, you could use

	LOOKFOR=$*[$#]

instead of that horrible awk.

*beats self upside the head*

All I can claim as an excuse is that I've been up until about 6 or 7 all  
week working on a report

Oh!  Nifty!  Will do....

I still use /bin/sh for most scripting things so I haven't learned much of  
the zsh-isms.....
